Special Issue Information

Dear Colleagues,

It is well known that more than 90% of water in the world comprises salty water and only about 2.5% could be used for human consumption; among that 2.5%, most water resources are polluted by various industrial dyes, toxic metallic ions, drugs, pesticides, bacteria, and other aromatic organic chemicals. Polymeric membranes provide a potential way to treat these pollutants in wastewater to obtain cleaning drinking water. Traditional polymer membranes have been widely used for water purification, but they are mostly limited by low selectivity, solution fluxes, and fouling issues. In addition, some impurities and biological materials would aggregate on the surface or in the pores of fabricated membranes, causing very poor selectivity, low water purification ability, reduced resilience, and increased energy consumption. The functionalization of polymer membranes with suitable chemicals, nanoparticles, and 2D graphene-like materials exhibits the possibility to create functional antifouling and antibacterial membrane materials. To promote the applications of polymer membranes in environmental science, other relevant issues on the membrane fabrication, characterization, physicochemical properties, processability, reliability, sustainability, and other factors should be understood in more depth.

Therefore, in this Special Issue on polymeric membranes, we would like to collect contributions that focus on (but are not limited to) the design, fabrication, structural and functional regulation, as well as application of various polymeric membranes in chemical engineering and environmental science. Submissions in the form of full-length articles, communications, and reviews are invited.

Lithium–sulfur (Li-S) batteries are considered one of the most promising energy storage systems due to their high theoretical capacity, high theoretical capacity density, and low cost. However, challenges such as poor conductivity of sulfur (S) elements in active materials, the “shuttle effect” caused by lithium polysulfide, and the growth of lithium dendrites impede the commercial development of Li-S batteries. As a crucial component of the battery, the separator plays a vital role in mitigating the shuttle effect caused by polysulfide. Traditional polypropylene, polyethylene, and polyimide separators are constrained by their inherent limitations, rendering them unsuitable for direct application in lithium–sulfur batteries. Therefore, there is an urgent need for the development of novel separators. This review summarizes the applications of different separator preparation methods and separator modification methods in lithium–sulfur batteries and analyzes their electrochemical performance.
